We DO NOT punish you with ridiculous re-stock fees if there is a mistake for purchases of mufflers, catalytic converters & pipes. If you made the mistake we only want to be reimbursed for our shipping cost and $5.00 for packaging. If it's our mistake we'll fix it, its that simple. So, before you buy anything at any web site check their re-stock fees.
